IMPROVEMENT lN STEERING APPARATUS.

Specification forming part of Letters Patent No. 141,95 8, dated August 19, 1873; application filed May 24, 1873.

more quickly than by other apparatus of this class.

' In the accompanying drawing, Figure 1 is a vertical longitudinal section of Fig. 2, taken on the line a: 00. Fig. 2 is a sectional plan view on the line y y, Fig. 2.

Similar letters of reference indicate corre sponding parts.

A is the steering-wheel. B is the steeringwheel shaft. 0 is the supporting-stand, in which the shaft revolves. D represents the deck of the vessel. E is a casing placed upon and attached to the deck, having a top, F. G is a bracket rigidly attached to the top F, the end of which supports the point of the wheel-shaft, as seen at H. I is the bevel'pinion on the wheel-shaft, which meshes into the bevel-wheel J of the vertical shaft K. The upper end of this shaft is supported by the bracket G, as seen at L. Its lower end revolves in a boX in the lower part of the casing, as seen at M. Nis aspur-pinion on the vertical shaft K. O O are horizontal rack-bars, with which the pinion N engages, and which receive an alternate horizontal motion as the pinion is turned in either direction. These rack-bars slide in" grooves in the casing E, and are confined by the top F. P is a yoke, which is rigidly attached to the top of the rudder-post. Q is the rudder. It R are slots or grooves in the top of the yoke. S S are swivel-blocks on the ends of the rack-bars, which rest in the grooves. The swivel-pins allow the yoke to vibrate without binding, while the blocks have a slight movement in the slots.

The operation is readily understood from the drawing. It will be seen that the movement of the steering-wheel is instantly imparted to the rudder. There is no slack or take-up when the motion of the wheel is reversed, and the wheelsman has a more complete control over the rudder than he has by the ordinary apparatus.

Having thus described m y invention, I claim as new and desire to secure by Letters Patent' The combination of the blocks S S working in slots of the yoke 1?, the rack-bars O O, the

spur-gear M, and the shafts B K and their connections, as shown and described, operating as specified.
